Mountain Bike Pre-Ride Checklist: 10 Quick Checks
Most trailside breakdowns can be spotted before you ever leave the parking lot. A loose wheel, a worn brake pad or a tire that has been slowly losing air all week will announce itself at the worst moment, usually halfway through the loop and far from your car.
A quick pre-ride check takes about two minutes and quickly becomes a habit. Here is a simple 10-point checklist you can run through before every ride, plus a few things to check less often.
Start with the Classic "ABC" Check
Many riders learn the ABC check: Air, Brakes, Chain. It covers the three things most likely to ruin a ride. The checklist below expands on it.
The 10-Point Pre-Ride Checklist
1. Tire pressure
Squeeze each tire and check it with a gauge if you have one. Mountain bike tires run much lower pressures than road tires, and the right number depends on your weight, tire size, tire type and the terrain. Too much air makes the bike skittish on roots and corners. Too little risks pinch flats, rim damage or the tire rolling in corners. Find a starting pressure that works for you and use it consistently.
2. Tire condition
Spin each wheel and look at the tread and sidewalls. Watch for cuts, bulges, embedded thorns or glass, and worn-out knobs. If you run tubeless tires, remember that sealant dries out over time and needs to be topped up periodically.
3. Wheels secure
Check that thru-axles or quick-release levers are fully closed and tight. Lift the front of the bike and give the wheel a firm tap downward. Nothing should rattle or shift. A loose front wheel is one of the most dangerous problems a bike can have.
4. Wheels true and spokes tight
Spin each wheel and watch it pass the brake caliper or frame. A noticeable wobble or rubbing means the wheel may need truing. Gently squeeze pairs of spokes. If any feel loose compared to the others, have them checked.
5. Brakes
Squeeze both brake levers hard. They should feel firm and stop well before touching the handlebar. If a lever feels spongy or pulls all the way to the bar, do not ride until it is fixed. Roll the bike forward and apply each brake to make sure it actually stops the wheel. Listen for grinding, which can mean worn pads.
6. Brake pads
Look into the caliper if you can see the pads. Most pads should be replaced once the pad material gets thin. Contaminated pads, from oil or chain lube, can also squeal and lose power.
7. Chain and drivetrain
Look at your chain. It should be clean and lightly lubricated, not dry and rusty or caked in grime. Shift through the gears on a quick spin around the lot and listen for skipping, clicking or grinding. A chain that skips under pressure may be worn or need an adjustment.
8. Headset and suspension
Hold the front brake and rock the bike back and forth. A knock or clunk from the front of the bike can mean a loose headset. Push down on the fork and rear suspension a few times. They should move smoothly and return without strange noises or leaks. Check your suspension air pressure if you have not recently.
9. Bolts and cockpit
Stand in front of the bike, hold the front wheel between your knees and try to twist the handlebar. It should not move. Check that the stem, handlebar, seatpost and saddle are tight and that brake and shifter levers are where you want them. If you have a dropper seatpost, make sure it goes up and down properly.
10. Pedals, shoes and you
Spin the pedals and make sure they are tight in the cranks. If you ride clipless pedals, check the cleats on your shoes. Then check yourself: helmet on and adjusted, gloves, glasses, water, food and your repair kit. Our essentials list covers what to carry.
Quick Reference
| Check | What you are looking for |
|---|---|
| Air | Correct pressure, no cuts or bulges, sealant topped up |
| Wheels | Axles tight, wheels spin straight, no loose spokes |
| Brakes | Firm levers, strong stopping, pads not worn |
| Chain | Clean, lubed, shifting smoothly |
| Front end | No headset knock, suspension working |
| Bolts | Bars, stem, seatpost and pedals secure |
| Rider | Helmet, water, repair kit, phone |
After the Ride
A few minutes after the ride can make your next pre-ride check even quicker:
- Wipe down the bike, especially the chain, fork stanchions and brakes. Avoid blasting water directly into bearings.
- Re-lube the chain once it is clean and dry.
- Note anything that felt off during the ride so you can fix it before next time.
Things to Check Less Often
- Chain wear with a chain checker tool. Replacing a chain on time can save your cassette and chainrings.
- Tubeless sealant level every few months.
- Bearings in hubs, bottom bracket and suspension pivots for play or roughness.
- Suspension service intervals recommended by the manufacturer.
- Brake bleed if your hydraulic brakes feel inconsistent.
- Bolt torque on critical parts, using a torque wrench.
If you are not sure how to do any of these, a local bike shop can help, and more experienced riders in the RBRTC Facebook group are usually happy to share tips.
Do Not Forget to Check the Trail
Your bike is only half the equation. Before heading out, check whether the trail is open and dry. For the trails RBRTC maintains at Lake Milton and Beaver Creek, look for condition updates in our Facebook group. Riding wet trails damages them; see why that matters.
Frequently Asked Questions
How long should a pre-ride check take?
Once it becomes a habit, about two minutes. The first few times will take longer while you learn what normal looks and feels like on your bike.
What should I do if something fails the check?
If it is a simple fix, like low tire pressure or a loose bolt, fix it in the parking lot. If your brakes feel soft, a wheel will not tighten or something cracks or wobbles, do not ride. Get it looked at first.
Do I need special tools?
A pump with a gauge and a good multi-tool cover most pre-ride fixes. A torque wrench and chain checker are useful additions for home maintenance.
Summary
Before every ride, check tire pressure and condition, make sure wheels are secure and true, test your brakes, look at your chain and shifting, check the headset and suspension, tighten the cockpit and pedals, and make sure you have your helmet, water and repair kit. It takes two minutes and saves a lot of walking. If you are new to the sport, our beginner's guide is a good next read.
